I am working on a new cnc mill. It is a RF31 Clone that I bought from wholesale tool a few years ago, but the new part is the CNC. Due to the cold in the shop this time of year I am taking some indoor time and wiring up a new controller this weekend in my home office. Sure beats the 14 degrees outside.
I am using 3 G203V's, a CNC4PC breakoutboard (the C10), and a 48 watt power suppply from Keling. I am also using an independent 5V supply that I got from MPJA.
On the geckos I have:
Pins 1 and 2 of the geckos to the 48 volts of the power supply,
Pins 3- 6 to the stepper motors
Pin 7 is empty
Pin 8 & 9 to the breakout board for step and direction. These are wired to pins 2&3 for x, 3&4 for y, and 5&6 for z.
What do I do with pin 10 (common)? I am almost positive that this should be a +5v supply. Is this correct? If so, should I get this from the +5V coming off the 5 v power supply or can I also get it from common connections on the BOB?
Pins 11 and 12 I have open as my motors are rated at 7 amps
Please double check my thinking and verify that I have all pins correct. Also let me know if I am correct in my thinking for pin 10 of the gecko.
